Subject

Caused by PR 2950, the styling of the CSS-class input-group-addon are not the default one defined by Bootstrap - Input groups. To get the default look of Bootstrap I have to set:

.input-group-addon
{
    width: 1%;
}

IMHO a default behaviour should always be extended rather than overwritten.

Steps to reproduce

Create an Admin with 'percentage'-FormType:

<?php
namespace AppBundle\Admin;

use Sonata\AdminBundle\Admin\AbstractAdmin;
use Sonata\AdminBundle\Form\FormMapper;

class MyAdmin extends AbstractAdmin
{
    /**
     * @param FormMapper $formMapper
     */
    protected function configureFormFields(FormMapper $formMapper)
    {
        $formMapper
            ->with('Form', [
                'class' => 'col-xs-6',
            ])
                ->add('titel')
                ->add('field', 'percent', [
                    'data' => 1,
                    'mapped' => false,
                ])
            ->end()
        ;
    }
}

Expected results

Actual results

If some fields are rendering correct and others not, it shouls be easily fixable by looking at what is missing on the percent field type. Probably some selector in css is not considering it.

Edited: its not that easy

Is this still relevant? If so, what is blocking it? Is there anything you can do to help move it forward?
